Initial results of combined anterior mitral leaflet plication and ventricular septal myotomy-myectomy for relief of left ventricular outflow tract obstruction in patients with hypertrophic cardiomyopathy.

Abstract

Mitral valve plication combined with myotomy-myectomy in obstructive HCM 1) can be performed safely and does not adversely alter mitral valve function, 2) relieves symptoms and outflow obstruction under basal and provocable conditions, and 3) may represent an alternative to mitral valve replacement in selected patients with elongated and enlarged mitral leaflets.
